NEW YORK, N. Y., A CORPORATION OF NEW YORK.

BLADE-HOLDER FOR SAFETY-RAZORS.

Specification of Letters Patent.

Patented May 9, 1916.

To all whom it may concern Be it known that I, HENRY J. GAISMAN, a citizen of the United States, and resident of New York city, borough of Manhattan, in the county of New York and State of New York, have invented certain new and useful Improvements in Blade-Holders for Safety-Razors, of which/the following is a specification.

My invention relates to holders for blades, and has particular reference to detachably holding blades in safety razors.

The object of my invention is to provide improved means for securely retaining a razor blade in position in a holder and to permit ready removal of the blades from and their insertion into the holders.

My invention comprises novel details of improvement andcombinations of parts that will be more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings forming part hereof wherein,

Figure 1 is a face view of a safety razor provided with my improvements; Fig. 2 is an enlarged face view of a portion of the blade holder; Fig. 3 is an edge view of 2;' Fig. 4 is a central sectional view of Fig. 3; Fig. 5 is a section on the line 5, 5, in

Fig. 1; Fig. 6 is a view similar to Fig. 5,V

showing the holder expanded to admit or release a blade; Fig. 7 is a section on the line 7, 7, in Fig. 2; Fig. 8 is a section on the line 8, 8, in Fig. 2; Fig. 9 is a face view of a portion of lthe holder, looking from the opposite side of Fig. 1; Figs. 10 and 11 are perspective views of the holder-operating.

lever, and Fig. 12 is a face view of a blade.

Similar numerals of reference indicate corresponding parts in the several views.

The blade holder shown comprises two opposed jaws or members 1, 1a placed side by side to receive between their separated edges a blade 2. The jaws 1, 1a are shown connected at their inner or loweinparts by the web 1", shown suitably folded to receive the blade-holder supporting-shaft` 3, to which the blade holder may be secured in any well known manner.

The parts 1, la, 1b of the holder are preferably made of a Single pieceof suitable metal stamped and folded in the manner shown, whereby suitable resiliency of the jaws 1, 1a is provided tending normally to Cause said members t0 close to clampthe blade between them. Means are provided on the jaws of the holder to retain the blade firmly in position between the jaws, and to spread said jaws apart to release the blade and permit insertion of a blade between the jaws. To this end I have shown a lever 4 pivotally supported between jaws 1, 1a and projecting beyond the corresponding ends thereof. The lever 4 has a portion 4a adapted to lie between adjacent ends of jaws 1, la, and adapted to enter the notch or recess 2, in the adjacent end of blade 2, to act as a stop or abutment to retain the blade in the holder. The outer portion 4b of lever 4 serves as a finger piece or handle to permit rocking of said lever. The part 4a of lever 4 is shown offset from the plane of the part 4" of said lever, and the latter part is shown provided with an opening 4% adapted to receive the tongue or projection 1c of holder jaw 1, which latter, adjacent to the end of member 1, is shown bent or recessed at 1d to serve as a seat for the lever. The inner end of lever 4a is adapted to bear against holder jaw 1, so that when said lever is swung from the position shown in Fig. 5, approximately to the position shown in Fig. 6, the jaws 1, l will be spread apart. The jaw 1a at its end is provided with a stop or inturned portion 1c adapted to engage the inner end of lever 4 to limit the outward swing thereof. Said end portion of jaw la is also shown bent outwardly or recessed at 1t to accommodate the end of lever 4a, thereby enabling the latter to be relatively long from its pivotal point, and yet not to unduly expand the holder jaws 1, la. The upper marginal end portion 1g of jaw 18L is shown bent inwardly to overlie lever 4 to aid in retaining the same in position, and the lower bent portion 1g of jaw la may serve a similar purpose. l

The device, as described, may be similar at opposite ends of the blade holder, and the blade be provided with notches or recesses 2a at opposite ends to coact with the corresponding levers 4, whereby when the blade is between holder jaws l, l and the ends 4a of said levers are turned so `as to enter the notches in the ends ofthe blade, the inward spring tendency of jaws 1, 1a of the holder will grip the blade, and will also grip lever ends 4, whereby the blade is retained in position in the holder. When it is desired to remove the blade, one or both of the levers 4 are turned to substantially the position shown in Fig. 6, whereby one or both ends of 'jaws l, la will be separated or expanded to release the blade, the lever end or ends 4a thereupon moving out of the recess or recesses 2a at the end or ends of the blade, and the blade may be removed. In such positions of the parts the blade may be inserted between jaws 1, l, and the levers turned to the positions shown in Figs. 1, 2, 3, 4 and 5, to cause gripping and retaining of the blade. The parts 4a of the lever constitute stops upon the blade holder to prevent movement of the blade, and the gripping of the jaws 1, la upon the blade retains the same lirmly in position in the holder.

In addition to the notches 2a in the ends of the blade I have shown the blade provided with an aperture 2b disposed preferably midway between notches 2, 2, adapted to receive a projection a upon one of .the holder jaws. For this purpose I have shown holder jaw 1a depressed at a to pass into the aperture 2b in the blade, and the jaw 1 depressed at b in register with the projection a to accommodate the latter, whereby the projection a when the blade is properly in position between the stops or levers 4a, will enter the aperture 2". This arrangement not only aids in retaining the blade in position between the holder jaws 1, l but overcomes danger that the blade will not be pro erly set in position in its holder, by reason of the fact that unless the projection a registers with the opening 2b in the blade, the holder jaws 1, 1a will notl close properly upon the side faces of the blade, and the entering of projection a in aperture 2b of the blade assures the proper location of the notches or recesses 2a at the ends of the blade in position to receive the ends 4a of levers 4.

The blade holder above described may be used in safety razors, and is particularly ladapted for use in the Auto Strop safety razor invented by me.

As illustrative of the adaptability of my improved blade holder for Safety razors, I have illustrated a frame having the base 6 and side uprights 68L extending therefrom, upon which the shaft 3 is journaled, a handle 7 being secured to frame 6. The numeral 8 indicates the well known stop engaging roller having gear 9 meshing with gear 10 on shaft 3 for rocking the blade `holder and blade for stropping the latter,

rollers 11 being carried by the frame as usual for tensioning a strop.

While I have illustrated my improvements in connection with the Auto Strop safety razor, it will be understood that the same may be used whether the blade holder Vbe adapted to rock or not.

Changes may be made in the details of construction and arrangements of parts shown and described, within the scope of the appended claims, without departing from the spirit of the invention.

Having now -described my invention what I claim is l. A blade holder having a pair of normally approaching jaws to receive a blade between them, and means movably mounted on one of the jaws coacting with the other jaw to spread said jaws apart to receive or release a blade, combined with a blade having a notch at one end adapted to receive said jaw operating means to aid in retaining the blade between said jaws.
